It seems George is becoming a popular name for aristocratic babies. After the Duchess of Cambridge gave birth earlier this week, the makers of ITV hit show Downton Abbey - filmed at Highclere Castle in Hampshire - have revealed Lady Mary Crawley's son is also called George.

But is seems Downton producers were first to pick the name as filming started months ago. The fictional baby George was apparently named after King George V.
